TILL-LOCK.

SPECIFICATION forming part of Letters Patent No. 421,287, dated February 11, 1890.

Application filed December 7, 1889. Serial No. 332,883. (No model.)

To all whom it may concern:

Be it known that I, GEORGE J. KELLER, of Osceola, in the county of Polk and State of Nebraska, have invented certain new and useful Improvements in Combination-Locks for Money-Drawers; and I do hereby declare thefollowing to be a full, clear, and exact deconnected to these levers, hand-levers, rods connected to and operated by the levers, and an alarm, as will be more fully described hereinafter.

The object of my invention is to provide a money-drawer with three separate sets of levers, so that any one or more of one of the sets of levers may be thrown out of the combination, so that should any one not knowing the combination attempt to open the moneydrawer he will only lock it and at the same time sound an alarm.

Figure 1 represents a vertical section of a lock which embodies my invention. Fig. 2 represents an inverted view of the same. Fig. 3 is a plan view of the same.

A represents the top of a counter, B the front of the money-drawer, O the back, and D its bottom. Placed inside of this drawer are the two supports or standards 13, through which the pivotal rod X is passed, and pivoted upon this rod X are a number of T-shaped levers A, which are weighted at their upper outer corners or ends, and which have their lower ends project .down through suitable slots in the bottom D of the drawer. Oon= nected to the lower ends of each of these levers A, which are to be used in the combination, is a connectingrod M, which has its outer end attached to an operz'tting hand-1ever K, which is pivoted on the under side of the drawer. There is an operatin g-1ever K for each one of the levers A. andD, and each of these levers is separated from the ones next for the pnrpose of holding the locking-levers in position. 6

Secured to the under side of the counter is a triangular-shaped block Q, behind which the locking-bolts catch for the purpose of locking the drawer, and which block is made inclined, as shown, on its under side, so that the locking-bolts C will be automatically depressed as the drawer is pushed back into position, and then made to snap up behind the rear end of the block Q by the weighted ends of the levers A. When the hand-levers 7 5 K of the levers A which are in the combination are operated, the lower ends of the levers A are drawn outward toward the operator, thereby raising the weighted ends of the levers A and depressing their rear ends, and thus drawing the locking-bolt O downward from behind the block Q.

Vhen any one or more of the levers A are not to be used in a combination, the rod M is disconnected from their lower ends and connected to the operating-rods N, and then the lower ends of the levers A are forced outward toward the front end of the drawer and the locking-slides V are moved forward and fastened so as to lock the levers A in position. These slotted locking-slides V are supported upon a supporting-bar W, which extends across the under side of the drawer, and which is provided with supportingflanges for catching against the lower sides of the slides V. After the slides V have been moved backward so as to lock the levers A in position, the set-screws which pass through the slots in the slides are tightened. When the levers A are thus thrown out of the combination, the locking-levers 0 connee-ted to them are held down so that they will not strike against the block Q. Also placed. upon. the top of the drawer are suitable standards or supports G, through the upper ends of which is passed a pivotal rod Y, upon which the L-shaped levers D are pivoted. The lower ends of these levers D pass through slots in the bottom D of the drawer, while to their upper ends are connected locking-bolts E. Only one or two of these levers D are brought into use when a corresponding number of the levers A are thrown out of the combination.

When a lever D is to be brought into use, the rod M, which is disconnected from the lower end of the lever A, is connected to an operating-rod N, which is pivoted at its rear end to the lower end of an alarm-lever F. Through each of these rods N is made a slot, which corresponds to one of the levers D, and the lower ends of the levers D are passed through slots, so that when the corresponding hand-levers K and rods M N are operated the alarm-levers F, which are pivoted in the bearings H, and the levers D will be operated. The lower ends of the levers D are not connected to the rods N, but simply passed through slots in the rods N, and through the lower ends of the levers are passed supporting pins or rods a, which prevent the rods N from dropping down when not in use.

When the rod N is drawn forward by the lever K, the lower end of the lever D is drawn forward, thereby raising the lockinglever E, so as to catch behind the block Q, and thus prevent, the drawer from being opened. At the same time the upper end of the lever F is moved backward, so that the ball or knocker upon its upper end will strike against a metal plate I, which is pivoted upon suitable supports J' upon the back 0 of the drawer.

If a person not familiar with the combination should attempt to open the drawer and either operate all of the levers K or one of them which has been thrown out of the combination, the lever D is operated so as to throw up a locking-bolt E, and thus prevent the drawer from being opened, at the same time that a lever F is made to strike against the plate I and sound an alarm. If only the levers K which are in the combination are operated, the lovers A are made to depress the locking-levers C, while those levers A D F which are not in the combination will not be touched at all. If, however, a person not familiar with theeombination happens 'to strike one of the levers K not in the combination, he both locks the drawer so that it cannot be opened and sounds an alarm at the the same time.

As shown in Fig. 2, six sets of levers are used and only four of them are in the combination, while the other two sets are thrown out. A person in opening the drawerhasbut to operate the four levers K in the combination and the drawer will open without any opposition whatever.

I do not limit myself to any precise number of sets of levers, for these may be varied indefinitely. The number of levers which are thrown out of the combination, or the arrangement of them, is a mere matter of choice.

Having thus described my invention, I elaim- 1. The combination, with a money-drawer and a block or stop secured to the under side of a counter, of a set of weighted levers A, having their lower ends to project through the bottom of the drawer, the locking-levers 0, connected thereto, the operating-levers K, connecting-rods M, the pivoted levers D, the locking-levers E, connected thereto, the operating-rod N, the levers F, and an alarm, substantially as shown.

2. The combination, in a money-drawer, of a set of weighted levers A auda corresponding number of L-shaped levers D, the locking-bolts C E, connected to these levers, the alarm-levers F, the connecting-rods M N, the operating-levers K, and an alarm, substantially as described.

3. The combination of a set of weighted levers A, locking-bolts 0, connected thereto, the L-shaped levers D, the locking-levers E, connected thereto, the operating-rods M N, the alarm-levers F, the alarms I, the lockingslides V, and the operating-levers K, sub stantially as set forth.

In testimony whereof I aflix in presence of two witnesses.

GEORGE J. KELLER.
